How do I resolve the unresolved external symbol linker errors:

1>prob8-6.obj : error LNK2019: unresolved external symbol "int __cdecl strcmp(int *,int *)" (?strcmp@@YAHPAH0@Z) referenced in function _main
1>prob8-6.obj : error LNK2001: unresolved external symbol _c
1>prob8-6.obj : error LNK2001: unresolved external symbol _b

The "strcmp" function is for comparing char array's, not integers. If you're trying to see if two numbers are the same then why not use the '==' operator?
